Inventor: SUGIHIRA KICHISABUROU
IPC: B23D49/14
Filed: 1979-09-17
Abstract: PURPOSE: To prevent from the occurrence of whitening phenomenon at a notched portion, by a method wherein a notched portion is formed in a plastic material extruded in a hollow plate using a punch provided with saw blades, whose cross section is of a U-shape, at the lower end of the punch.  
     CONSTITUTION: A nothced portion is formed in a plastic made material 1, extruded in a hollow plate, by the use of a punch 5 having saw blades 6 at the lower end thereof, the saw blade being formed such that a side thereof is formed in a triangle which has an acute angle at its point, a saw blade is provided on a sloping surface, and a cross section thereof is of a U-shaped. A notching tool 9, consisting of the raw material 6 and the punch 5, mounted at a press machine is lowered. Straight line portions 10 and 11 of a channel 3 are first cut by means of the blades 6, and a curved portion 12 is finally cut by means of a point of the punch 5. This permits the formation of the notched portion in the plastic material extruded in a hollow plate without the occurrence of a whitening phenomenon.

Title: Two-stroke cycle engine
Inventor: CHIN SHIGENOBU
IPC: F02B25/16
Filed: 1994-05-10
Abstract: PURPOSE: To obtain a high efficiency two-stroke engine by fitting a piston which divides the inside of a cylinder into a combustion chamber and an air chamber, into the cylinder having a peripheral wall and end parts so that it can freely reciprocate, and converting reciprocating motion of the piston into rotary motion. CONSTITUTION: With this engine, the inside of a cylinder 10 is divided into a combustion chamber and an air chamber by a double-head piston 12 fitted in the inside of the cylinder. Further, an exhaust port 32 is formed in the peripheral wall of the cylinder 10 so that it is adjacent to a first end part, an intake port 34 is formed so that it is adjacent to a second end part, and a scavenging conduit pipe 40 and an intake conduit pipe 50 are further provided. When power stroke is started, the exhaust port 32 blocked by the piston skirt is opened to shift to exhaust stroke, and then the scavenging conduit pipe 40 is released to shift to scavenging stroke, and to shift to fuel/air injection stroke thereafter. Thus, a mixture is injected from a jet 56 into the combustion chamber, and is ignited by a spark plug 30.

Title: Non-contact transmitting device
Inventor: WAKABAYASHI NAOYUKI
IPC: G07B15/00
Filed: 1992-04-13
Abstract: PURPOSE:To minimize the reception voltage fluctuation due to distance variation, to simplify the circuitry of the reception circuit on the medium, and to decrease the cost by the unique constitution to reduce the transmission current as the medium approaches the transmitter. CONSTITUTION:As a non-contact ticket 6 as a medium approaches a transmission antenna 7 in an automatic ticket gate machine 2 as a transmission section, a coupling coefficient K between coils 9 and 13 becomes large so that the mutual inductance M becomes gradually larger. Transmission current I which is almost proportional to the value of the voltage V divided by the square of the mutual inductance M is reduced as the distance decreases. As the non- contact ticket 6 being the medium approaches the transmitter antenna 7, the transmitter current I decreases but the input voltage E is kept from dropping by a voltage drop preventing resistor 18, thus the received input voltage E fluctuation due to the distance between the transmitter antenna 7 and the receiver antenna 12 is decreased. The magnetic field H of the coil at the receiver antenna 12 side and the received voltage E can be prevented from excessively increasing as before, due to the gradual decrease of the transmission current I.

Abstract: PURPOSE: To calculate the position of an error by a few number of operations by correcting an error position discovery equation each time the root of the equation is discovered, and reducing the number of Galois area multiplication and addition required for calculating the value of a remaining X as a possible solution. CONSTITUTION: Whether or not various X are the roots of an equation is judged by substituting the coefficient of the equation and the continuous values of the X for a series of V pieces of error discover formulas. When the X is not the root of the equation, a new X value is substituted for the formula, and a sum δv' is calculated, and compared with 0. The output of an asserted AND gate 32 is added through a delay circuit 33, a clock 34 is reset, and a new value X=(α<i+1> is loaded from a computer 36 to a register 38. In this case, the value of the X loaded in the register 38 is evaluated as a possible root. When the X is a root, the coefficient of the equation is corrected, and the order of the equation, that is, the value of V is decreased by one.

Thereafter, the similar processing is repeated for the portion of input data and parity data and after final shift, whether the outputs of the latch 43 are all zero or not is inspected by an error judging circuit 71. Then, the result of entirely being zero is judged to be no error but the results excepting for it are judged to have an error and are outputted from an output terminal 72.

Abstract: PURPOSE:To form a good welding bead on both surface and reverse side, by using a copper material, and a composite core wire containing a flux, for a backing material and a welding core wire, respectively, and executing single side welding at a specified torch angle. CONSTITUTION:Welding is executed by using a copper plate or a copper alloy as a backing material 7, butting an object to be welded 1 on a groove 8 of the backing material 7, generating a welding arc 5 between a welding core wire 6 containing a flux and the object to be welded 1, and setting a torch angle to 2 deg.-10 deg. angular advance. In this case, the flux of the welding core wire 6 is melted earlier than a metal of the welding core wire 6, and a back slag 9 is formed in the groove 8. A molten metal flows into the groove 8 after the back slag is formed, and a back bead 3 is formed. Therefore, the back bead 3 becomes very smooth since the molten metal is not quenched by the copper plate 7. Also, a part of the flux forms a coating surface slag 10 on a surface bead 4, and a good surface bead 4 is obtained.
